Amy could tell from the way the Doctor looked deep in thought when she showed up, that he was probably trying to work things out. Figure out how to get them all out of this Red Oak place, so they weren't really trapped here. It was enough to ease some of that worry she had about being stuck here forever, although some of it was still there, under the surface. Because she was behind the Doctor, from the past in his time line, she didn't know about how he fixed the cracks in the universe, but she was no longer assuming it was the cracks that brought them all here.
For a minute, Amy was about to make a face about how sitting around in a library wasn't exactly an adventure, unless it was the library of the TARDIS, because at least there was a swimming pool, but he quickly changed gears and she had to grin at him. "Something of interest?," she questioned with a bit of a cheeky smirk, because 'something of interest' for them could mean entirely different things. "With a giant robot roaming about, a dragon that sleeps in one of the parks sometimes and with what happened at the ball, we should be able to find something," she amended a moment later, nudging him a bit as she said it because she was with the Doctor. Of course they'd find something strange and interesting and likely a bit weird.
